it b all whom it may concern I lie it known that l, l-lun'r lDInonnrcr-r, a citizen .of the United @tates, residing at lllew York city in the county of New York and State of New York, have invented new and useful Improvements 1n Electric Lamps and lfians, of which the followmg isa specilicationi c i This invent1on relates to an ornamental and useful device embodylng an electric lamp and a rotary fan, the object of the de- 'vlce being to provide an Ornamental device which may beused. as an electric lamp or as an electric fan, or may be used. s11nultaneously as a fan and lamp.

The devicehas a casing of a form similar to the Dutch windmills and upon the out-- side the fan which completes the appear ance of a windmill, while at the same time benng capable of cooling the air in the usual manner of an electric fan. A portion of the casing 15 prov1ded with openlngs and the electric lamp is positloned within the casing so as to cast rays of light through the openings and across the fan. The appearance of the device, with the rays of light shining ion'the blades of the fan, is

very artistic and attractive, while at the same tnnelt provides a very compact and CODVGIllBHt means for lighting and cooling it T001111;

l-l guardis also provided around the fan,

said. guard constitutin in effect? a switch,

it being necessary that said guard shall always he in place around the fan before the motor can be started and fan operated. The guard when lowered. represents a rustle fence extending around the base of the windmill; a c

The invention consists in the combination and arrangement of parts setforth in the following specification and. particularly pointed out in the claims thereof.

the windmill. it cylindrical. sleeve 6 en circles the cylindrical portion 4: ofthe cas i and is slidablevertically thereon. When n its lowered position itrests as shown in the shaft of an electric motor 16.

An. electric lamp 17 is held in a socket 18 which is supported upon a brace 19 fastened to the upper end of the frusto-conical portion 3.

it guard 20 is provided to prevent accidents resulting from coming in contact with the fan, said guard consisting of annular members 21 and 22 between which extend at regular intervals rods 23. The guard 20 is supported and pivoted at 24; upon a bracket 25 fast to the front of the windmill, and is further supported from above by means of a brace 26 which has attached-thereto a.

plug 27 adapted to fit a socket 28 constructed of insulating material and located at the apex of the roof 5 of the windmill. The plug 27 and socket 28 constitute a switch and it is necessary that the electric circuit hereinafter to be described shall always be completed through this switch before the fan can be operated.

When it is not intended to operate the fan, the guard 20 may be lowered by removing the plug 27 from the socket 28 and allowing said guard to drop to the position illustrated in dotted lines at which time said guard represents a rustic fence extending around said windmill. a

The device is operated and controlled by electric circuits as follows: Upon the interior of the windmill is located a switch 29, the said switch being fastened to theinside of the frusto-conieal portion 3 of the casing. The switch 29 includes an insulating plate 30 provided with terminals 31 and 32. to which are connected wires 33 and 34-, which, in turn, are connected to a suitable source of electric power 35, The switch 29 further 7 wire 45 with the contact plate 36, and the contact arm 38 is connected. with the terminal 32 by a wire 46. The electric lamp 17 is connected by wires 47 and 48 to the terminal 31 and contact plate 37 respectively.

A door 49 is hinged at 50 to the frustoconical portion of the casing and is held closed by means of a latch 51. Said door is made ofrustic design and appearance and provides a means of access to the electric switch 29 whereby the electric circuits may be controlled.

The general operation of the device is as follows: If it is desired to use the device simply as a fan without the light, then the sleeve 6 is pushed upwardly to the position shown in the drawings and the openings 4 are thus closed. The guard 20 is next raised into position to surround the fan 8 and the Y plug 27-is inserted in the socket 28, thereby connecting the terminals 43 and 44. The electriemotor 16 is then set in operation by opening the door 49 and moving the contact arm 38 of the switch 29 into engagement with the contact plate 36. This completes the independent fan operating circuit. The fan, may be stopped at any time if desired bysimply removing the plug 27 from the socket 28.

If it is desired to use the device as a lamp and fan combined, the contact arm 38 is moved so that it will not only engage the contact plate 36, but it will also engage the contact plate 37. In this manner the fan operating circuitis completed. At this time the cylindrical sleeve 6 is in its lowered position resting'npon the annular support 7. If

'it is desired to stop the fan during the times when the fan is in operation and also when the lamp is lighted, it is only necessary to remove the plug 27 from contact with the ter minals 43 and 44, thereby breaking the fan circuit'but leaving the lamp circuit completed. V r

If it is desired to use the electric lamp alone, and have the fan remain stationary, the guard 20 is preferably lowered to the position illustrated in dotted lines. This will cause the fan circuit to be broken between the terminals 43 and 44 and make it impossible for the fan to again be operated until the guard 20 is again placed in position. It'is preferable at this time to have the contact arm 38 in engagement with the contact plate 37 only,'although it is not necessary. .In each case the lamp circuit 7 only is completed.

It will thus be seen that my device is not motor to said fan, whereby a rotary motion may be imparted thereto, and an electric lamp located within said casing and positioned to cast rays of light through said openings and across said fan.

2. A device of the character descrilmd having, in combination, a hollow casing provided with openings, an electric motor within said casing, a fan rotatably mounted on the outside of said casing in alincment with said openings, a member constructed and arranged to either constitute a guard for said fan or a fence around said hollow c. sing, means connecting said motor to said fan whereby a rotary motion may be imparted thereto, and an electric lamp located within said casing and positioned to cast rays of light through said openings and across said fan.

3. A device of the character described having, in combination, a hollow casing provided with openings, an electric motor within said casing, afan rotatably mounted on the outside of said casing in alinement. with said openings, means connecting said motor to said fan whereby a rotary motion may be imparted thereto, and an electric lamp located within said casing and positioned to cast rays of light through said openings and across said fan. said electric lamp being in a separate electric circuit from the circuit which includes the motor.

4. A device of the character described having. in combination, a base. a frustoconical body portion fast to said base, :1 cylindrical. body portion located above said frusto-conical portion. a conical top located above said cylindrical portion. a fan rotatportion, said cylindrical portion being provided with openings, a cylindrical sleeve slidably mounted upon said cylindrical portion, a fan rotatably mounted on said cy lindrical portion in alinernent with said openings, an electric motor located upon said base, means connecting said motor to said ilitll whereby a rotary motion may be imparted thereto, and an electric lamp located Within said cylindrical portion posi- 10 tioned to. cast rays of light through said openings and across said fan, said electric lamp being in a separate electric circuit from the circuit which includes the motor.

In testimony whereof, I have hereunto set 15 my hand.
